IMPROVEMENT IN GAS-LIGHTING TORCHES.

Specification forming part of Letters Patent No. 215,329, dated May 13,1879; application filed February 6, 1879.

To all whom it may concern:

Be it known that LJnssE ORANNELL, of Troy, New York, have inventedcertain new and useful Improvements in Gas-Lighting Torches, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, and the letters of reference markedthereon, which form a part of this specification.

Figure 1 represents the gas-lighting torch complete, with holderinflated and ready for use; and Fig. 2 represents the same after the gasin the holder has been exhausted.

The object of my invention is to produce a cheap, reliable, and simplegas-lighting torch without using wick or wax tapers or any othersubstance likely to drip during combustion; and the nature of itconsists in providing the stem or handle ofthe torch with a smallelastic gas-holder, which can readily and quickly be filled from anygas-burner, and with an elastic band or spring for compressing theholder and producing the necessary pressure upon the gas within theholder, and to make a jet of gas at the tip of the torch.

A is the hollow stem of the torch, made of metal, and passing entirelythrough the holder B, the edges of the openings in the holder beingfirmly and closely secured around such Stem.

G is a stop-cock in the stem, located between the ,holder and the tip ofthe stem, to stop the flow of the gas from the holder.

B is the gas-holder, made of rubber or other elastic material capable ofsecuring within its walls hydrocarbon gas.

D is an elastic band around the holder, for compressing the holder afterit has been inflated with gas, and for insuring a steady flow of gasthrough the tip when the stop-cock G is open, so long as any remains inthe holder.

E is the inlet-pipe, through which the gas is conveyed from thesupply-pipe or burner into the holder, and is closely secured in theholder at any convenient point between the stop-cock G and the stop-cockH.

H is a stop-cock in the inlet-pipe, to prevent the flow of gas back fromthe holder after inflation.

At the lower part of the stem a handle is secured, and at or near thetop of the stem the ordinary key for opening and closing the stop-cocksin the gas-fixtures may be located. The part of the stem Within theholder is pierced with holes, to admit the gas from the holder into thestem.

The operation is as follows: The stop-cock H being open, the inlet-pipeis slipped over the supply-pipe or over an ordinary gasburner, and thegas admitted to the holder, the ordinary pressure at the source ofsupply being sufficient to inflate the holder. After the holder has beenfilled the stop-cock H is closed, and the torch is ready for use.

A holder six inches in diameter is sufficient to hold gas enough to feeda small jet for an hour or more, an d sufficient for lighting a greatmany burners.

A torch made and supplied in this manner has many advantages over theordinary torches supplied with alcohol or wax tapers, 860. It is simplein construction, will not easily get out of order, no wax or othersubstance to drip, and no smoke during combustion. The stem can also bemade very light, and it can be along stem for reaching gas-burnersplaced at high points. or long stems may be substituted for short onesby putting a screw-coupling in the stem above the holder.

This torch will be very light, and when inflated will be still lighter,and can be easily handled by any person.

I am aware that rigid tubes or reservoirs have been used for thispurpose, and also that flexible bulbs have been used for extin guishin gpurposes, said bulbs being pressed or contracted by the hand, and alsothat a spring has been placed within a flexible bag, said bag beingoperated by the spring for dis charging the gas, and I do not thereforeclaim such as my invention, in which is generally used a bulb much toolarge to be grasped by the hand; but,

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. An elastic bulb or reservoir, B, and devices for filling the samewith hydrocarbon gas, in combination with an elastic band to furnish therequired pressure, substantially as described.

2. The elastic reservoir B and the band D, in combination with the tubeA and stop-cock O, substantially as and for the purpose set forth.
